interface MigrateProcessInterface in Zircon Profile 8.0

An interface for migrate process plugins.

A process plugin can use any number of methods instead of (but not in addition to) transform with the same arguments and then the plugin configuration needs to provide the name of the method to be called via the "method" key. See \Drupal\migrate\Plugin\migrate\process\SkipOnEmpty and migrate.migration.d6_field_instance_widget_settings.yml for examples.
